SEWING-MACHINE.

Specification of Letters Patent.

Patented Feb. 6, 1906.

Original application filed September 16, 1903, Serial No. 173,410. Divided and this application filed July 7, 1904. Serial No. 215,599.

To (0U ZUZ'I/O'HY/ 717'; may concern:

Be it known thatI, CHRISTIAN PEDERsEN, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Sewing-Machines, of which the following is a full clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a side elevation, partly in section. Fig. 2 is a front elevation, partly in section. Fig. 3 is a top plan view, partly in section, the housing-plate 125 being shown in open position by dotted lines. Fig. 4 is a longitudinal sectional elevation through the wax-pot, its inclosing walls, and other parts adjacent thereto; and. Fig. 5 is a transverse sectional elevation through the wax-pot and its inclosing walls.

This invention relates to sewing-machines, and more particularly to the structure of a wax-thread sewing-machine to provide for the heating of the wax-pot and the thread. The object of the invention is to provide a convenient structure whereby a single source of heat supplies heat to the wax-pot and also to the thread and the machine elements at the point at which the stitch is formed.

To these ends and also to improve generally upon machines of the character indicated the invention consists in the various matters hereinafter described and claimed.

The present application is a division of my application for patent upon sewing-machines filed on or about September 16, 1903, Serial No. 173,410.

Referring now more particularly to the drawings, 1 represents the supporting-base, which has a rectangular top 2, upon which latter are end plates 3, supporting an upper rectangular supporting-frame 4, from whose center rises a head-frame 5, a rear housingplate 3 extending about the rear of the machine between the said end plates 3 and the frames 2 and 4. The main shaft 8 is journaled in the said end plates 3. The worktable is shown at 46. The rotary shuttle 11 is supported in the said head-frame 5 and is constructed and driven from the shaft 8, as fully disclosed by patent to Whipple, No. 730,848, dated June 9, 1903. Upon the front of the frame 4 are standards 16 and 17, the

said frame being cut away between said standards, and extending between these standards and across the space in said frame 4 between them is a support 18, upon which are mounted the awl-carrier 23, carrying the awl 24, the presser-foot carrier 29, with its presser-foot 34, the needle-carrier 31, with its needle 53, and the needle guide 59. The thread-laying devices 84 and 90 and the loopspreader 63 are mounted in proximity to the needle and the shuttle, and the thread-guide pulley 117 upon the take-uplever 116 is in substantially vertical alinement with the needle and the shuttle. These various elements are actuated as fully described in my said prior application, of which the present case is a division, the manner of their operation being immaterial so far as the present case is concerned.

The wax-pot 9 is supported upon the standard 1 below the main shaft of the machine and is a part of the casting, which also includes side walls 10 and front and rear walls 10 and 10*, respectively, which depend. about said wax-pot, the lamp, gas-jet, or other appropriate source of heat being supported in any suitable manner so that its upper end is slightly above the bottom edge of said. depending inclosing walls, the flame being thus surrounded by said walls. In this wax-pot 9 is a thread-guide 118. The thread from the supply 119 passes about this thread-guide 118, through the wax-pot, thence over the thread-guide 120 at the front of the machine, thence upwardly over a thread-guide 121 at the front of the machine, thence downwardly and about the pulley 1.17 in the take-up lever, thence upwardly through the thread-eye 90 in the thread-carrier 89, and thence to the work.

In the present machine the head-frame 5 projects at the front, so that the shuttle is substantially above the needle and the awl, and the thread between the guide 120 and the thread-eye 9O lies substantially below the needle and the shuttle. The forward wall 10 about the wax-pot and surrounding the flame is slotted, as shown at 122, and a plate 123, curved upwardly and outwardly, extends from said wall and has its ends connected to the latter by end walls 124, a flue from the heat-receiving space inclosed by the walls 10, 10, and 10 being thus produced. Hinged to the frame of the machine at a point near the forward edge of each forward end plate 3 is a housing-plate 125, whose free edge extends to substantially the vertical plane in which the thread a: is included, the portion of each housing-plate near its free edge being bulged outwardly, as shown at 126, so that when these plates are swung together they produce a flue which incloses the thread between the thread-guide 120 and the threadeye 90, the needle and the shuttle lying directly above the open upper end of said flue. A flue-section having a front plate 127 and side plates 128 is hinged between lugs 129 upon said end plates 124, and when this fluesection is swung upwardly its upper end is received inside of the flue produced by the extending portions 126 of the housing-plates 125, and this flue-section connects the flue produced by said housing-plates with the flue produced by the plates 123 and 124. A suitable latch 130 serves to lock the housingplates 125 together. A deflector-plate 131 extends immediately below the thread-guide 120 in order to protect the thread upon said guide from heat thrown into the before-mentioned flue.

Rods 132, journaled in the front and back walls 10 and 10 have deflector-plates 133 carried thereon, said plates terminating a short distance from the front wall 10 of the pot, so that a space is provided through which the heat can pass into the flue formed by the housing-plates 125 to keep the wax on the thread extending from the guide 120 to the thread-eye 90 in a plastic condition. The ends of these rods extend beyond the front wall 10 and are upturned to produce handles 134, these handles being preferably weighted, as shown at 135, to retain the deflector-plates in open and closed position. When the machine is to be started, the handles 134 are thrown outwardly to carry the deflectorplates away from each other, and thus leave the bottom of the wax-pot 9 directly exposed to the heat from the heater. After the wax in the pot has been sufliciently heated, however, the deflector-plates 133 are thrown into closed position to diminish the quantity of heat to which the bottom of the pot 9 is subj ected, and thus keep the wax in the pot at a proper temperature. The heat passing up the flue also flows upon the needle and shuttle, so that a single source of heat serves to heat the wax in the pot and also keep the thread in a properly-heated condition while being operated on.

I am aware that minor changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

1. In a sewing machine, a support, an overhanging head-frame, a shuttle in the overhanging head-frame, a needle cooperating with. said support and substantially in alinement with said shuttle, a Wax-pot below the needle and shuttle, a flue leading from said wax-pot to said needle and shuttle, a

source of heat beneath the wax-pot, and pivoted deflectors interposed between the source of heat and the wax-pot substantially as described.

2. In a sewing-machine, a support, stitchforming members thereon, a wax-pot below said stitch-forming members, a housing surrounding the wax-pot and depending therefrom, a flue leading from said housing to said stitch-forming members, and pivoted deflectors movable to positions to permit the source of heat to act directly upon the wax-pot and movable to positions to deflect the heat from the wax-pot and through the flue; substantially as described.

3. In a sewing-machine, a support, stitchforming members thereon, a wax-pot, walls depending about the same and adapted to inclose a heater, one of said walls having an opening, a flue-section leading through said opening, housing-plates upon said support forming a flue leading to said stitch-forming members, and pivoted deflectors interposed between the wax-pot and the heater for deflecting the heat from the wax-pot; substantially as described.

In testimony whereof I hereunto aflix my signature, in the presence of two witnesses, this second day of July, 1904.

CHRISTIAN PEDERSEN.
